“…Although the impact of O. beta on the native fish fauna is still unknown (Caires et al 2007), it is supposed to be serious, as it is a voracious, generalized predator (Gray & Winn 1961). Moreover, recent field observations have already reported O. beta as a very common by-catch in long-line inside estuary, thus affecting local fisheries.…”

Abstract:The objective of this work was to present an updated checklist of the currently known fishes in the Paranaguá Estuarine Complex (PEC) and provides comments on conservation status for the treated species. We used a large dataset derived from a pool of studies which have been conducted within there along the last 30 years. Each study was based on monthly samplings and conducted in several estuarine habitat; thus, the pool covers practically all estuarine habitats and takes into account the seasonal cycle in the system. The PEC ichthyofauna represents a mixture between that fauna typical from the tropical Brazilian coast and that with affinities of temperate Argentinean and Uruguayan zones. The PEC harbors a rich fish fauna of 213 species, inserted in the families that are common along the Brazilian coast. Only a minor part (8%) of the PEC fish fauna was evaluated as regards the conservation status, mostly because of the lack of basic biological and ecological information for most species. Despite part of the among-estuaries differences are due to different and incomplete sampling efforts, the richness in the PEC is surprisingly higher than other systems in Brazil and around world, which emphasize the importance of the region for global biodiversity conservation. Resumo: O objetivo deste trabalho é apresentar uma lista de espécies atualizada a partir do conhecimento atual dos peixes no Complexo Estuarino de Paranaguá (CEP), com comentários sobre o status de conservação das espécies. Nós utilizamos um grande conjunto de dados derivados de diversos estudos conduzidos na região ao longo dos últimos 30 anos. Cada estudo foi baseado em amostragens mensais realizadas em diferentes habitats estuarinos. Dessa forma, os dados abrangem praticamente todos os habitats estuarinos e leva em conta o ciclo sazonal no sistema. A ictiofauna do CEP representa uma mistura entre a fauna típica da costa tropical brasileira e da fauna com afinidade com as zonas temperadas argentinas e uruguaias. O CEP abriga 213 espécies, inseridas em famílias que são comuns ao longo da costa brasileira. Apenas uma pequena parte (8%) das espécies foi avaliada quanto ao status de conservação, principalmente por causa da falta de informações biológicas e ecológicas básicas para a maioria das espécies. Apesar de parte das diferenças entre estuários ser devido a diferentes e incompletos esforços amostrais, a riqueza do CEP é surpreendentemente elevada em comparação com outros sistemas do Brasil e ao redor do mundo, o que enfatiza a importância da região para a conservação da biodiversidade global.

“…This richness is higher than, or comparable to, those of other systems located in species-rich, tropical biogeographical zones around the world, which emphasizes the importance of PEC for global biodiversity conservation (PASSOS et al, 2012). Despite this conservation status, PEC has suffered from the impact of three ports (Paranaguá, Antonina and Ponta do Félix), dredging, discharge of domestic and industrial effluents, introduction of exotic species (VITULE et al 2006;CAIRES et al, 2007;CONTENTE et al, 2011b), and growing urbanization (LANA et al, 2001). The structure and composition of the fish assemblages along the east-west salinity gradient of the PEC, and their relationship to the abiotic factors of beaches (GODEFROID et al, 1997;FÉLIX et al, 2006;FÉLIX et al, 2007a, b;HACKRADT et al, 2011), rivers (CONTENTE et al, 2011a, tidal creeks SPACH et al, 2004a, b;) and tidal flats (FALCÃO et al, 2006;FALCÃO et al, 2008; has been widely studied, primarily using taxonomic metrics.…”

A B S T R A C THere we test the effects of the east-west salinity gradient in the subtropical Paranaguá Bay Estuarine Complex (PEC) on the structure of shallow water fish fauna, determined according to taxonomic (families and species) and functional composition metrics. A total of 152 species were observed. The families with the largest number of species were the Sciaenidae, Carangidae, Haemulidae and Gobiidae. The most abundant species were Atherinella brasiliensis, Harengula clupeola, Anchoa januaria and Anchoa tricolor. Marine stragglers dominated in number of species, followed by marine migrants and estuarine species. Most species were zoobenthivores, followed by piscivores and zooplanktivores. Families and species more frequently associated with estuarine conditions dominated in the mesohaline sector, and those more frequently associated with marine conditions dominated in the euhaline sector. The fish assemblages along the estuarine salinity gradient were found to be better characterized by taxonomic metrics than by functional ones. This is most likely because individuals of all functional groups inhabit all salinity sectors, and thus these metrics are not useful for differentiating assemblages along salinity gradients. Our results differ from those of other studies in tropical and subtropical estuaries, which have emphasized the importance of functional groups in determining fish assemblages along salinity gradients. R E S U M ONeste trabalho foi testado o efeito do gradiente de salinidade do eixo-leste oeste do sistema subtropical Complexo Estuarino da Baía de Paranaguá na estrutura dos peixes de águas rasas, determinado de acordo com as métricas taxonômica (famílias e espécies) e de composição funcional. Um total de 152 espécies foi registrado. As famílias com maior número de espécies foram Sciaenidae, Carangidae, Haemulidae e Gobiidae. As espécies mais abundantes foram A. brasiliensis, H. clupeola, A. januaria e A. tricolor. Os visitantes marinhos dominaram em número de espécies, seguidos pelos migrantes marinhos e estuarinos. A maioria das espécies são zoobentívoras, seguidas pelas piscívoras e zooplanctívoras. As famílias e espécies mais relacionadas com condições estuarinas dominaram no setor mesohalino e aquelas mais relacionadas com condições marinhas dominaram no setor euhalino. A métrica taxonômica foi mais eficiente na caracterização das assembleias de peixes ao longo do gradiente estuarino de salinidade do que a funcional. Isso ocorreu principalmente porque indivíduos de todos os grupos funcionais estiveram presentes ao longo de todos os setores de salinidade, invalidando o emprego dessa métrica na diferenciação das assembleias nos diversos setores. Nosso resultado foi diferente do encontrado em outros estuários tropicais e subtropicais, que enfatizaram a importância dos grupos funcionais na estruturação das assembleias de peixes ao longo de um gradiente de salinidade.

Morphometric measurements, meristic counts and DNA barcoding identified the presence of a biglip grunt Plectorhinchus macrolepis in the western Atlantic Ocean. As the species is endemic to the tropical eastern Atlantic Ocean and has not previously been reported in the western Atlantic Ocean, we discuss the possible means by which it might have dispersed to the western Atlantic Ocean. Even though this species is not considered established in Paranaguá Bay, we advocate monitoring of possible new individuals and other exotic fish species.
